Abstract (en)

[origin: EP3934085A1] A power conversion apparatus 1 includes a U-phase positive-side direct current bus bar 41P, a U-phase negative-side direct current bus bar 41N, and a U-phase parallel connection bus bar 4101 connecting a plurality of positive-side terminals 410P, negative-side terminals 410N, and alternating current output terminals 4100, respectively, of switch modules 410 with each other, and these bus bars constitute a U-phase laminate bus bar 41PNO of a laminated structure stacked with an insulating layer 4111 interposed therebetween. A connection portion between the U-phase parallel connection bus bar 4101 and the U-phase output bus bar 4102 is arranged at a position farther away from a smoothing circuit 20 than is a semiconductor switch 410s farthest from the smoothing circuit 20 among multiple switch modules 410.
